Benefits of technology

The present technology is about improving wound dressing compositions by adding carboxy methyl cellulose, oxidized regenerated cellulose, and silver. The compositions may also contain non-gelling cellulose fibers, oxidized regenerated cellulose complexed with silver, and a hydrogel. These compositions can be used as an absorbent layer in a dressing and may include collagen and other wound healing active materials. The technology provides better wound care by promoting faster healing with these improved dressing compositions.

Problems solved by technology

Such wounds may be the result of trauma, surgery, or disease, and affect skin or other tissues.
Infections can retard wound healing and, if untreated, can result in tissue loss, systemic infections, septic shock and death.

Abstract

Wound dressing compositions comprising: carboxymethyl cellulose, oxidized regenerated cellulose (ORC), and silver. The dressings optionally further comprise non-gelling cellulose fibers. The compositions may comprise a complex of the ORC and silver. Wound dressings are also provided, comprising an absorbent layer comprising the wound dressing compositions.

Description

RELATED APPLICATIONS[0001]The present invention claims the benefit, under 35 USC § 119(e), of the filing of U.S. Provisional Patent Application Ser. No. 62 / 310,270, entitled “Antimicrobial Wound Dressing,” filed Mar. 18, 2016. This provisional application is incorporated herein by reference for all purposes.TECHNICAL FIELD[0002]The present technology relates to compositions and devices, including wound dressings, for application to wounds.BACKGROUND[0003]A wide variety of materials and devices, generally characterized as “wound dressings,” are known in the art for use in treating an injury or other disruption of tissue. Such wounds may be the result of trauma, surgery, or disease, and affect skin or other tissues. In general, dressings may control bleeding, absorb wound exudate, ease pain, assist in debriding the wound, protect wound tissue from infection, or otherwise promote healing and protect the wound from further damage.[0004]In particular, many wound dressings protect, or ass...
